xDrive the permanent all-wheel drive system from BMW: under normal circumstances, it distributes driver power between the front and rear axles in a 40:60 ratio, and changes this figure variably when the road surface or overall driving conditions change. Acting virtually instantaneously and a manner so subtle as to be go virtually unnoticed by the vehicle’s occupants, xDrive can direct up to 100% of drive forces to one axle. Enabling the driver to start up effortlessly even on slippery surfaces or steep hills, xDrive routes all power to the axles with the greatest traction. When parking, the system reacts to the need for high manoeuvrability at low speed by opening the clutch completely so the powertrain functions optimally. At the first sign of understeering, drive power to the front axle is reduced. If oversteering is detected, xDrive directs more power to the front axle. Thanks to this dynamic redistribution of power, vehicle stability returns to normal even before the driver notices anything amiss. :: Click for detailed xDrive information Xenon Headlights Also Known as HID (High Intensity Discharge) lights. Named for the inert gas they employ to amplify light produced by electricity jumping between two electrodes. HID lights don’t use a filament, as do incandescent headlights, and they tend to last two to three times longer. They also provide much more uniform intensity. Aim a set of xenon headlights at a wall, and you’ll see they define a sharp line at the top of the projected light pattern rather than the gradual fade common to conventional headlights. HID lights produce ultraviolet as well as visible light, which makes reflective highway signs glow more brilliantly. :: Click for detailed Xenon Headlights information
